.ATEI FFICEQ JOHN J. IIENNESSY, OF NENV KENSINGTON, PENNSYLVANIA.

SPINNING TOP.

SPECIFICATION forming part of Letters Patent No. 695,930, dated March25, 1902.

Application filed May 11,1901. Serial No. 59,759. (No model.)

To all whom it may concern:

Be it known that I, JOHN JAMES HENNESSY, a citizen of the United States,and a resident of New Kensington, county of Westmoreland, and State ofPennsylvania, have invented certain new and useful Improvements inSpinning-Tops, of which the following is a specification, referencebeing had to the accompanying drawings, forming a part thereof, in whichsimilar characters of reference indicate corresponding parts;

This invention relates toimprovements in spinning-tops of the characteradapted to automatically produce a musical or whistling sound whilespinning; and the object thereof is to provide a device of thischaracter which is durable, inexpensive, and continuously effective ingeneral operation.

The invention will be hereinafter fully described, and specifically setforth in the annexed claims.

In the accompanying drawings, forming part of this specification, Figure1 is a plan view of my improved top; Fig. 2, a side elevation thereof,and Fig. 3 a vertical sectional elevation taken on a line as w of Fig.1.

In the practice of my invention I employ primarily a solid wooden bodyof the ordinary conical or approximating conical contour and having ametallic spur or point 1 to bear the impact and contact with a surfaceduring the operation of spinning the top. Formed in the center of thetop at its upper part is a cylindrical recess a, having a concave lowersurface a and an annular groove a Extending downwardly from this saidrecess is a cylindrical channel B, which leads in a vertical directionapproximately to the center of the top and communicates with a pluralityof radially-extended air passages b. Secured within the recess a is awhistle O, which embodies the apertured convex disks 0 c. This whistleis securely held in place by means of the spring-metal split ring D,which engages the groove a of the recess a and contacts with the uppersurface of the whistle 0, whereby said whistle is securely retainedwithin the recess a and is not liable to be displaced by the operationof spinning the top. I

In the operation and use of the invention the top is spun by means of acord in the usual and well-known manner, and while the top is spinningair passing through the whistle O and the air-passages B and 1) causesthe whistle to automatically produce a sound.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. As a new article of manufacture, a top having a vertical centralopening, a plurality of radial openings leading therefrom through thesides of the top, a vertical central recess communicating with the saidvertical central opening and having a concaved bottom and an annulargroove, the bottom of said recess adapted to engage a whistle havingaconvex surface, and the annular groove adapted to engage a fasteningdevice for securing the whistle,substantiallyhs shown and described.

2. The combination, with a top having a vertical central opening, aplurality of radial openings leading outwardly therefrom, a verticalcentral cylindrical recess communicating with the said opening and whichhas a concave bottom and an annular groove, of a whistle embodying twoconvex disks secured together at their meeting edges, and aspringfastener engaging partly within the said annular groove and partlyover the top edge of the whistle, whereby said whistle cannot be shakenout of place and it is located for protection with' its top surfacebelow the upper surface of the top-body, substantially as shown anddescribed.

3. The combination, with the top A, having the vertical central openingB, and a plurality of radial openings 1), leading outwardly therefrom,the cylindrical recess a, having the concave bottom a',and the annulargroove (0 of a hollow whistle embodying two convex disks centrallypierced and secured to each other at their periphery and fitting snuglywithin the bottom of the recess, and means embodying a split ringengaging within the groove and over the edge of the whistle to keep saidwhistle securely in place, substantially as shown and described.

In testimony that I claim the foregoing as my invention I have signed myname,in presence of two witnesses, this 30th day of April, 1901.

JOHN J. HENNESSY.

Witnesses:

GEO. D. HAMOR, JAMES ODoNNELL.
